ExpertPower 12V Smart Lithium Battery Chargers

ExpertPower manufactures several battery chargers intended for charging Lithium Iron Phosphate (LiFePO4) batteries only using 2-stage Constant Current/Constant Voltage (CC/CV) charging cycles.

ExpertPower EPC122, EPC125, and EPC1220 feature maximum charging current of 2, 5, and 20 Amps respectively and are a good match for ExpertPower lithium LiFePO4 batteries, although they can be used for charging LiFePO4 batteries from other brands as well.

ExpertPower 12V Smart Lithium Battery Chargers Features and Specifications

ExpertPower 12V Smart Lithium Battery Chargers are designed for charging 12V Lithium Iron Phosphate batteries ranging from 4Ah to 100+ Ah.

ExpertPower lithium battery chargers are designed ONLY for 12V LiFePO4 batteries. They implement the special 2-stage 'Constant Current/Constant Voltage' (CC/CV) charging process - first, the battery is being charged with the constant current, second, the battery is being charged using constant voltage, while the charging current decreases over time.

Also, since the lithium-ion batteries come with the Battery Management Systems (BMS), the chargers are designed to reset all types of BMS.

The following comparison chart lists ExpertPower smart lithium battery chargers and their most important features and specifications.

Although these battery chargers are recommended for the batteries having a nominal capacity of 2x 'Charging Current', perhaps the safer option is to use them for batteries with a nominal capacity of at least 2.5-3x 'Charging Current'.

expertpower ep125 w200For example: while ExpertPower EPC122 (2 Amps charging current) is fine for EP125 (5 Ah nominal capacity), ExpertPower EPC125 may be slightly too strong for ExpertPower EP1210 - according to the manufacturer, ExpertPower EP1210 features a maximum charging current of 5 Amps which is the charging current of ExpertPower EPC125 and, in theory, everything is fine.

All ExpertPower lithium batteries feature intelligent Battery Management Systems (BMS) that protect the batteries, including from overcharging and overheating.

Note: It is the author's opinion that in real-life situations, it is sometimes better to avoid such 'matching' battery chargers and batteries - if You have an EP1210 battery, charge it with an EPC122 battery charger. IMHO, of course.


Long Story Short: If You are looking for a dedicated lithium battery chargers, not only for ExpertPower Lithium Iron Phosphate (LiFePO4) batteries, consider ExpertPower EPC122, EPC125, and EPC1220 battery chargers - they are very simple to use and maintain, and with two-stage CC/CV charging, they charge the batteries completely and even prolong their operating lifetime.

Just be sure to choose according to your own needs and requirements - i.e. battery capacity, maximum charging current, and similar.
